These are the instructions for creating an end-user VM from scratch.

VM Configuration

Base OS Install

There is a bug in virtual box with IPv6 handling over a bridged network.  When the bug is present the top transfer speeds for IPv6 are around 18kb/s.  Since RHEL (and derivatives) prefer IPv6 when looking up hosts, it is not uncommon to get an IPv6 host address for updates.  To disable IPv6 on the guest add these lines to /etc/sysctl.conf

net.ipv6.conf.all.disable_ipv6 = 1
 net.ipv6.conf.default.disable_ipv6 = 1


Avalon Install

Demo Content

VM Image Prep


Adding the demo batch increased the size of the VM download from 3.2G to 7.4G.  Partially its because we've make derivatives and there's really new content on the VM.  But for a bigger reason, any disk space that gets allocated is stored in the image file – the VM doesn't know what's being used and what isn't.  Since we download a largish package, untar it, and create a bunch of temp files, the VM disk image has a bunch of unused (from the OS point of view) disk that it still has to keep track of.  Future research should include how to 'unuse' the disk space.

"zerofree" should do the trick, when combined with vboxmanager modifyhd <name> --compact
